WASHINGTON — Leylah Fernandez collected the biggest title of her career at the D.C. Open with her most lopsided victory of the tournament, defeating Anna Kalinskaya 6-1, 6-2 in the final on Sunday.

Leylah Fernandez proved her resolve three times over on the way to the DC Open final — in two grueling matches against top-15 players and one against her former doubles partner and good friend, Taylor Townsend.

Leylah Fernandez will be trying to win her first WTA title of the season, and Anna Kalinskaya will seek the first of her career when they meet each other in the final of the hard-court DC Open.
